Sažetak
The Adriatic Sea is an epicontinental, closed sea, part of the Mediterranean. It was formed in the Late Miocene, and was structurally developed during the Pliocene and Quaternary, when most of the sediments were deposited. The larger Pliocene and Quaternary depressions are formed mostly at the western coast, where the sediments are several thousand metres thick, and originated from the Alps and the Apennines. The east coast is characterised by large and elongated the Dinarides Mts., but have extremely close continental drainage to shoreline and a very small erosional rate. Consequently, the eastern flows were and are very short, like estuaries with high tidal influence, eroding only small volumes of mostly carbonate detritus and closed with frontal islands or mountains, and very restricted depositional areas. The Neretva River sediments, part of the largest contemporary delta system on the eastern Adriatic coast, have been analysed in this study using three seismic sections and one exploration well. Those sediments are recognized as being inside the Neretva and Korčula Channels, assuming that the influences of Quaternary glacials have shifted the delta tens of kilometres to the west in the past on several occasions.
